Tecumseh AJ 2432 P-FZ (Old Code: CAJ 2432 Z) 3/4 Hp R-404A Refrigeration Compressor

Tecumseh's legendary CAJ 2432 Z model of French origin, one of the most reliable reciprocating models in the commercial refrigeration sector, is now manufactured under the code AJ 2432 P-FZ in line with the renewed global naming standards. This new model retains all the technical characteristics, mounting foot dimensions and performance values of the old version one-to-one, offering service technicians a trouble-free drop-in replacement.

Powerful 3/4 Hp LBP Performance and CSR Motor Design

Optimized for low evaporating temperatures (LBP), this 3/4 Hp hermetic compressor operates with R404A refrigerant. Thanks to its CSR (Capacitor Start and Run) type motor, it successfully meets the high starting torque and continuous operating stability required especially in commercial refrigerators, deep-freeze rooms and cold storage warehouses. With a cylinder displacement of 18.3 cm³, it ensures a stable refrigeration cycle.

Installation and Service Note for Refrigeration Technicians in the Field

Technician's Note: When using the AJ 2432 P-FZ model in place of the old CAJ 2432 Z, no modification is required; the connection valves and bolt positions are the same. However, during installation, care must be taken because of the moisture-absorbing property of the 887 cm³ of POE oil, and the system must be thoroughly evacuated. Replacing the filter drier is vital for a long compressor life. Do not forget to renew the Teflon seals that ensure tightness at the Rotalock valve connections at every replacement.
